Re: What happened?

The router reports no sync. Yes both connections are BTW via the same exchange.

I have tried re-booting the router.

My earlier post about no response from the Zen website was wrong. I had overlooked the fact that I set the Enternet router to route Zen data out through the Zen router even if I was using Enternet for everything else. The Zen website is fine. (also checked via a Vodafone mifi unit which I am using now)

Re: What happened?

No sync when another BT Wholesale connection at the same premises continues to work implies a failure in the MSAN line card port, your router, or the metallic pair in between the two. The cause could be technological or human error (mistaken cease, accidental or malicious tampering with the line).

It's probably worth ringing 17070 on the affected line and checking that you hear the phone number you expect, also that a quiet line test is OK. It's worth trying the test socket, a different cable between the socket and the router, and a spare router if you have one. If none of those work, it's a case of calling Zen.

My Zen connection has been working fine all day, as you can see in my BQM, though that means nothing in this context as it's a FTTC connection via the Zen backhaul network.

Re: What happened?

After a telephone call to Zen Support (talking to a very helpfull engineer), I now think that this is a BT line fault - the phone is now also very noisy and intermittent. (I did try swaping the routers/filters and a spare router - all with the same results)

As I do not need two ADSL connections at the moment, I am happy to leave things as they are ('phone and router disconnected) until after the new year - and then try 17070, etc. (The 'phone now has a divert from the bad line to the good one and all of my servers are happy just on the one working ADSL connection)
